I just ordered an Edimax EW-7611ULB wifi dongle for its bluetooth capability. It looks like the successor of Edimax EW-7811Un, although the wifi chip is different and it requires manual drivers installation.

I've had this adapter running on Raspbian w/kernel 4.9.35+ for more that a year in a Raspberry Pi A+ as an Internet radio box coupled to a BOSSE SoundLink mini. My original intention was to use Volumio for this Internet radio box but compiling the driver for Volumio turned out to be more than I could handle. I then decided to use MusicPlayer and compile th edirvet for Raspbian 4.9.35+. Unfortunately there is still an issue with the Edimax driver: I'm seeing a memory leak that will go on until the memory is depleted down to OS minimum and the MusicPlayer daemon stops.
Has anyone experienced this behavior with the Edimax driver? Can anyone give me some hints on how to debug this issue?
